Hi guys, I'm working on a carbon steel vessel with MDMT of -24degree C, the shell material is ASTM A516 Gr70 and the forgings/flanges are A105. I understand ASME B16.5 flanges are excepted from impact testing up to -29degree C. I've got a heavy neck forging of 152.4mm thk welded into the 35mm...

Hi, Can someone please tell me how to calculate a branched reinforcement when using a weldolet to connect the header to the branch. Secondly how can i determine the thickness of the weldolet to be used in my calculation. Many Thanks in advance Fizzy

Hi All, Can someone please throw more light on this or refer me to a text to help me clarify this with my client. i'm designing a vertical tower to the EN13445 code with severe blast loading on its supports resulting in an unrealistic thickness compared to the vessel. This is also not giving...

Hi All, I'm designing a pressure vessel to PD5500 with a MDMT of -45C which requires a 24"NB RFLWN manway with a 60mm thk nozzle neck. Enquiry Case 5500/87 of the code states a max thickness of 50mm for temp range of -50C to 0C. I'm assuming this statement is for the vessel shell/head as my...

Hi guys, I'm working on a vessel design which my client requires two half skirts welded on opposite sides of the dished head for its support. The vessel is a relatively small vessel (508mm OD) with two curved plates welded at opposite ends leaving the mid section open for access to the nozzles...

Hi all, I'm designing a high pressure vessel to EN13445 code which requires both support brackets and lifting lugs. I've completed my design based on internal pressure, external pressure, nozzle reinforcement etc to determine the thickness. On designing for the support brackets and lifting...

Hi all, I'm designing a vertical vessel to ASME VIII and my client wants me to include both the test pressure vertical (site) and the test pressure horizontal (shop). Can someone pls advice me on which one is 1.3xDesign pressure and how to determine the other one. Thanks in advance.

Hi All, Please i'm designing some lifting lugs on a horizontal pressure vessel and would need advice on calculating for the bearing (Hertzian) stresses and tension stresses.

Hi All, Pls can someone tell me how to calculate the anchor bolt load required to overcome saddle movement as a result of seismic load using ASME VII div 1. I'm working on a horizontal vessel of abt 15tonnes.
